When my now 14-year-old daughter was 3 and her younger brother was getting into everything, she asked, "Mommy, can we put him back, now?"
Deciding to take this opportunity as a teaching moment in how siblings should treat each other, I explained to her that we could not put him back - that her brother was a gift from God.
She looked up at me with her big blue eyes and responded, "I understand, Mommy. God didn't want him either."
